Excercise After PVD is Safe

A Posterior Vitreous Detachment May Cure VMT

I believe exercise after sustaining a posterior vitreous detachment (PVD) to be safe.  Many doctors recommend a "no exercise" period after a PVD to decrease the risk of retinal tear and retinal detachment.  This does not make sense to me. PVD Causes Retinal Tear A retinal tear may occur after a posterior vitreous detachment, but in my opinion, the chance of a tear … [Read more...]

Retinal Tears and Vitreous Hemorrhage

Vitrectomy for Retinal Tear to Remove Vitreous Hemorrhage

A vitreous hemorrhage may be caused by a retinal tear.  Sometimes there is so much blood in the eye that direct examination is impossible and we can only guess at the most likely cause.  It is the most difficult situation for me to handle as a doctor. Patients lose significant vision as the blood in the middle of the eye physically blocks all light from hitting the … [Read more...]

Floaters, Are They Normal or due to Diabetic Retinopathy?

Floaters are generically defined as black spots in your vision.  They move to and fro with eye movement.  Most of the time they are small, tiny and black, but really can be large and translucent, too.  From a doctor's standpoint, size does not matter.  New floaters can mean a retinal tear and the development of a retinal detachment. Floaters can develop from a variety … [Read more...]

Retinal Tears and Retinal Detachments

I just operated on a patient for a retinal detachment in his left eye. He had a previous retinal detachment repaired about 3 years ago. Three years ago, I repaired the retinal detachment by performing a vitrectomy in combination with a scleral buckle. When informed about the need for surgery in the left eye, due to the new retinal detachment, he asked if I had to … [Read more...]
